Today Reuters details new information from emails and other documents relating to further arrangements involving Manchester City.

The club was bought by Sheikh Mansour bin Zayed Al Nahyan, half-brother of the ruler of Abu Dhabi, in 2008.

Those arrangements boosted the club’s finances by tens of millions of pounds, helping it to buy star players.

Manchester City said in a statement responding to questions last month: “We will not be providing any comment on out-of-context materials purported to have been hacked or stolen from City Football Group and Manchester City personnel and associated people.

“The attempt to damage the Club’s reputation is organised and clear.”

The club did not respond to further questions put this month.

The club said in an April 2014 response to UEFA investigators about sponsorship that it had complied with the rules and “adopted a good faith and correct interpretation of the regulations.”

UEFA said in an emailed response to Reuters that it could not comment on specific cases due to confidentiality obligations.
